Thanks, Steve.
Originally posted by stevebrot It might also be noted that some simple circular metal hoods may well have adequate clearance.
Yes, but most, if not all, available are 58/62mm and don't fit. I already had that experience with metal hoods. The fixed one on the lens isn't that much wider than 58mm.
Above is a metal hood as mentioned, and below is the spacer ring (see attached picture). They're held in place by a cheap 58mm reverse filter K mount adapter (in order to put a filter between the subject and the exposed rear element and mount). I ordered it as a 12mm Ř58mm spacer, but as you can see, it came marked as "for canon G15 58mm", so you might get lucky going that route and get a better deal.
It's just a matter of trial and error. A step up ring on top of the spacer and using 62 mm cap and thin filters might work. But it's certainly pushing the limits. As it is, I don't get any vignetting at f/22 on my Pentax film cameras. At least on digital, you can remove any in pp software, maybe if it appears strongly between f/1.8-8.
